Many manufacturing processes require precise control of high pressures. It’s not difficult to find high pressure mechanical regulators, but it can be very difficult to find electronic controllers that can handle more than 1,000 PSI…and most are designed for much lower pressure. With Proportion-Air’s high pressure ratio regulator assemblies, pressures up to 7,500 PSI (and more) can be controlled with only shop air. That means we can use our standard electronic pressure regulators as pilots, controlling dome pressure to a high pressure ratio regulator.
